Meat Slicer? – Cooking Fever: Restaurant Game Review

Excited about the Smokey Grill BBQ. I updated my meat slicer to the fullest and it says 4 portions at once, but I can only put 2 slabs of meat on at a time which I had already been doing with the 2nd upgrade (I think). I don't know if it's a glitch, if I'm trying to put the meat on wrong, or if I'm just confused.
